Fields

Field	Takes	Meaning
size	"small" \| "medium" \| "large" default "small"	AWS: cache.t4g.micro, .small, .medium. Google Cloud: 1, 2 or 5 GB, basic tier. Azure: Basic C0, C1, C2. Must be written out.

Any other field is refused (AK204), and the error names the exact type to declare with node for the setting you wanted.

What it becomes

Cloud	Becomes
AWS	An ElastiCache Redis cluster, one node.
Google Cloud	A Memorystore for Redis instance, basic tier.
Azure	An Azure Cache for Redis, basic SKU.

Joins the shared network net: all three clouds.

What a connection hands over

An env connection to a cache gives the consumer these variables, each prefixed by the cache's name in upper case — cache "orders" gives ORDERS_…:

Cloud	Variables
AWS	`_HOST, _PORT, _URL`
Google Cloud	`_HOST, _PORT, _URL`
Azure	`_HOST, _PORT, and _PASSWORD through the secrets channel`

Notes

Replicated or clustered tiers are provider settings: declare the cache with node to choose one.
